HAND-STAMP.

SPECIFICATION forming part of Letters Patent No. 417,278, dated December1'7, 1889.

Application filed March 28, 1889. Serial No. 305,135. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE D. PRINGLE, jeweler, of the city of Guelph,in the county of \Vellington, in the Province of Ontario, Canada,haveinvented a certain new and useful Improvement in Rubber Stamp-Machines,of which the following is a specification.

This invention relates to that class of handstamps in which more thanone inscriptionplate is fixed to the same block; and the inventionconsists in the peculiar construction, arrangement, and combinations ofparts hereinafter more particularly described, and then definitelypointed out in the claim.

Figure 1 represents a perspective view of a rubber stamp-machineprovided with my improvement. Fig. 2 represents a similar view in areversed position.

A represents a rectangular block pivoted on the spindle B, which passesthrough the frame C and is provided with a knob D.

As illustrated in the drawings, my invention is applied to a self-inkingstamping-machine, and consequently the reversing-frame E is employed,and the inwardly-curved lip a is formed on the said frame. Thisinwardlycurved lip projects over the beveled edge 7),

formed on the block A and holds the said block stationary in theposition indicated. WVhen it is desired to turn the block so as to bringone of its other sides into position for work, the said block is turnedby seizing the knob D, and the frame E springs sufliciently to permitthe block A to pass over the inwardly-curved lip a, and springs backagain immediately that the beveled edge once more comes opposite to thelip.

I do not confine myself to any particular shape of block, as it may betriangular in form, rectangular, octagonal, or any other shape on whichmore than one rubber stamp may be fixed.

What I claim as my invention is- Apivoted block A, having the edges ofits end beveled at b, in combination with an inwardly-curved lip a,formed on the springframe E, substantially as and for the purposespecified.

Guelph, March 6, 1889.
